CZ fans know the line-up: the CZ 75 family on the hammer side, the P-10 on the striker side. The DUTY 4.0 is the next striker gun, and it brings a new architecture. The serial number now sits on an internal modular chassis, with a fiberglass-reinforced polymer grip frame around it, and the SFDA trigger has been refined to 5.6 pounds with 9 mm of travel and a 4 mm reset. The slide is direct-mount optics-ready, the sights fixed, the 4-inch barrel unthreaded.

Four models: C compact at 15+1 and 135 mm tall, F full-size at 17+1 and 143 mm, each with an MS variant that adds a manual thumb safety. For Kansas buyers from Overland Park and Kansas City to Wichita, Salina and Great Bend, it slots in as the home-defense or carry pistol next to a Scorpion-style 9mm carbine. This is an independent CZ-focused shop, not affiliated with CZ-USA, and the DUTY 4.0 is a $729 MSRP new release.

Pick the F when the gun lives on a belt or in a bedside rather than under a T-shirt. Over the carry-size it adds two rounds (17+1 against 15+1), about 8 mm of grip and 10 g of weight, and nothing else changes.

Where the P-10 had a registered polymer frame, the DUTY 4.0 moves the serial number to an internal modular chassis. That is the headline. The rest follows the modern service-pistol formula done carefully: a striker SFDA trigger at 25 ± 4 N (5.6 ± 0.9 lbs) (4 mm (0.16 in) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel), a 188 mm (7.4 in) long slide with direct-mount optics cuts, fixed sights and a 4-inch barrel without a thread.

No manual safety here. The firing pin block, trigger safety and trigger bar safety handle drop safety, and the holster handles the rest. CZ sells the same gun with a frame-mounted lever as the MS model.

Who is it for: the belt, the bedside and the range; the version to buy if you rarely need to hide the gun. If you already shoot a P-10, the DUTY is the next step in the same family, with a new chassis and the optics done right.

Pick the C, F or MS model and name the Kansas dealer you want it shipped to. Kansas has no purchase permit and no waiting period; your dealer runs the NICS check at pickup. Magazines, optics and ammo ship to your door. Live price and stock checks happen at order time, before payment.

Questions buyers ask: Do DUTY 4.0 magazines work in a P-10? CZ has not confirmed magazine compatibility with the P-10, so treat them as separate until CZ says otherwise. Buy DUTY 4.0 magazines for the DUTY 4.0. Does the DUTY 4.0 come with a manual safety? Only the MS versions have the thumb safety; the standard C and F rely on the firing pin block, trigger safety and trigger bar safety. How many rounds does the CZ DUTY 4.0 F hold? 17+1 with the standard magazine and 19+1 with the extended base plate.
